"errmsg" : "Our replica set config is invalid or we are not a member of it"

查看副本集状态，报错：

> rs.status();
{
"state" : 10,
"stateStr" : "REMOVED",
"uptime" : 93,
"optime" : Timestamp(1478239977, 594),
"optimeDate" : ISODate("2016-11-04T06:12:57Z"),
"ok" : 0,
"errmsg" : "Our replica set config is invalid or we are not a member of it",
"code" : 93
}

查看日志，发现：

2016-11-07T14:43:25.497+0800 W REPL     [ReplicationExecutor] Local replica set configuration document reports set name of MyReplset, but command line reports MyReplicate; waitng for reconfig or remote heartbeat

我之前启动mongo命令是：/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongod.cnf --repliSet MyReplset

这回命令是：/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongod.cnf --repliSet MyReplicate

所以两次指定的副本集名称不一致，导致出错。
